Be it known that I, Rosana W. LAwaoN, a

city and count of San Francisco and State of California, lave inventedcertain new and useful I'm rovernents in Hydrocarbon-Burners, of whichthe followin is a specification.

The hereinafter described invention" relates to an improved burner forthe supplying of an atomized hydrocarbon mixture as ing of that typedisclosed in United States L etters'Patent No. 1,020,612, granted untome under date of March 12, 1912, wherein takes lacean-intermixture ofoil, steam and air; t e object of the invention being to "produceabetter mixture of the-steam, air

.burner of Letters .Patent' I secure a com a'ct flame, to increase "thevolume of the ame and intensity of the heat and oil than is obtained bthe use of the thereof, to provide means whereby the flow of oil intothe burner may be readily 1ncreased and decreased in accordance with therichness of the mixture desired, and to overcome the-carbonizing ofthe'working parts of the burner.

To com rehend the invention reference I should be ad to the accompanyingsheet of drawings, wherein- Figure 1 is a vertical longitudlnalsectional view of the im roved burners. Fig.

2 is a detail View of t e nozzlezand its adjustable tip. Fig. 3 is aperspective view of the ejector tube for directing the mixturewithin thebonnet of the burner. Fig 4 is a front end elevation of the burner.

In the drawings, the numeral'l is used to designate a base preferably ofspherical form, the interior of which constitutes an air inductionchamber 2. From the said base outwardly extends diprojects ahonnet I 3,which when the burner is applied to a furnace projects within the firingchamber thereof. The bonnet 3is of tapering form, gradually enlargingtoward the discharge end thereof, aud'to impart a fan shape to the flameprojected therefrom the same is of elliiiticalshape in cross section. c

The base 1 is provided interior-1y with a rib or bridge 'piece 4 formedwith a screw threaded bore 5, into which screws the exteriorly threadedtubular end section 6 of an ejector tube, which inner end of .said tubeprojccts into air induction chamber generally, the burner be- Zef thebase 1 to within a 5116adram, of

Within the oil ,supply pipe isfitted an adjustable rod 11, which connects with the cone valve 12seated the said rod 11 is moved longitudinally within the oil pipe 10 inorder to adjust the .valve 12-! means ofthe adjusting hand wheel 13. 12the nozzle outlet ,8, there; from .the nozzle 7 may trolled for securingthe proper admixture of 'oil and steam and to regula e Qtlggintensity ofthe flame. r r; I

The base 1 isprovided with one or more air inlets 14, through which airis drawn into the chamber 2 for supplying the requisite oxygen to themixture as drawn into the ejectortube, which mixture is forcedunderpressure into and through said tube for discharge bonnet 3. Thesuction created by the mixture flowing through theejector tube drawslets 14, such air as does not intermix with' the atomized carbonaceousmixture [lowing 3 through the passage-ways l5 formu'dhy the bridge-piece4 for supplying the necessary oxygenfor proper com the air inlets 14 arecoutrolled by the ad'- justable dampers 15', so that the quantity ofair. drawn into thocluuulxar 2 may be regurtherewith the'outerjendsection 6' of said I ;tra1 openingI or'outletj 8 which is gradually IThe conicalfnozzlejsj.provided with a. rear- I f I in the flaring outlet8 of the nozzle 7, and r V y means of the adaustable valve be ijclidilyconignition-at the outer end thereof within the I air into the chamber 2through the" air ininto the ejector tube passes into the .bonnet ustion.Preferably,
